I am thinking about resigning from my current job .   Have you thought about it seriously ?   Yes , I have been thinking about it for quite a while . Now I finally make up my mind to leave . I have given my resignation letter to our boss last Friday .   Ok , did you find a new company ?   Yes , I will move on to XYZ Company .   Good for you , but your leaving will be a great loss to us . It is so nice to work with you .   Thanks . I had learned so much from you and our colleagues .
